The Greek philosopher Aristotle, who lived in the fourth century B.C., was interested in a large number of different subjects. In one of his books he dealt with the movements of physical objects, and here he said that heavy things fell faster than light things. It is unlikely that Aristotle tried to prove this by experiment; he was probably just repeating a common belief.
For 2,000 years everybody thought that Aristotle was right. However, in the 16th century scientists began to question a large number of old beliefs, and the Italian scientist Galileo Galilei carried out* various experiments on the dynamics of falling bodies. It is said that he dropped a cannonball and a pebble* from the top of the leaning* tower of Pisa to see which would reach the ground first. This may not be true, but we do know that Galileo proved that Aristotle was wrong; he showed that light and heavy things fell at the same speed.
Galileo was also interested in astronomy and optics. He improved the telescope, which had recently been invented, and he was the first person to use one of these instruments to study the sky. He found out that Jupiter had satellites, that Saturn had rings, that there were mountains on the Moon and spots* on the Sun.
Galileo got into serious trouble with the Italian universities and the Catholic Church, which preferred Aristotle’s picture of the universe, and he was made to stop telling people about his new discoveries.
